Pickle file and send via socket

[S.B]

Hello friends

Does anyone know if it's possible to pickle and un-pickle a file across a network socket. i.e: 
First host pickles a file object and writes the pickled file object to a client socket.
Second host reads the pickled file object from the server socket and un-pickles it.

Can anyone provide a simple code example of the client and server sides?

Thanks
